Abstract

Some properties of the Inflated Poisson distribution are discussed and the types of problems to which it could be usefully employed are outlined. The distribution is fitted to data on the number of eggs per floret of the clover seed moth, Coleophora alycyonipennella Kollar and shown to give a better fit than the simple Poisson and the Negative Binomial distributions based on x2 values from data for the period of greatest vegetative growth in the early summer of 1966–1967.
